Abstract

A striking degradation of phosphatidylcholine into phosphatidic acid was observed in the cortical tissues of less hardy poplar (Poplus euramericani cv. gelrica), when the tissues were frozen below a lethal temperature. No change in phospholipids was detected during freezing or even after thawing in the cortical tissues of hardy poplar which survived slow freezing to -30 C or even immersion in liquid N(2) after prefreezing to -50 C. The degradation of phosphatidylcholine during freezing appears to be intimately associated with freezing injury.

摘要

在组织被冷冻到致死温度以下时,脆弱的美洲黑杨(Poplus euramericani cv. gelrica)皮层组织中观察到磷脂酰胆碱明显降解为磷脂酸。在耐寒的美洲黑杨皮层组织中,无论是在冷冻过程中还是在解冻后,都没有检测到磷脂发生变化,这些组织能在缓慢冷冻到-30°C 甚至预冷冻到-50°C 后浸入液氮中存活下来。冷冻过程中磷脂酰胆碱的降解似乎与冷冻损伤密切相关。
